Estimation of the optimal ratio of standardized ileal digestible tryptophan to lysine for finishing barrows fed low protein diets supplemented with crystalline amino acids
tryptophan requirement pig performance
2015/7/3
Optimum standardized ileal digestible (SID) tryptophan (Trp) to lysine (Lys) ratio was estimated for 67–96 kg barrows fed low protein diets supplemented with crystalline amino acids (AA). One hundred ...
Effects of Forage:Concentrate Ratio on Growth Performance, Ruminal Fermentation and Blood Metabolites in Housing-feeding Yaks
Concentrate Ratio Growth Performance Ruminal Fermentation Yak
2016/5/19
The objective of this study was to determine the effect of forage: concentrate ratio (F:C) on growth performance, ruminal fermentation and blood metabolites of housing-feeding yaks. Thirty-two Maiwa m...
Effects of Benzoic Acid and Dietary Calcium:Phosphorus Ratio on Performance and Mineral Metabolism of Weanling Pigs
Benzoic Acid Calcium Bone Characteristics Pig
2016/5/16
In a 2×2 factorial experiment the hypotheses tested were that the metabolic acid load caused by benzoic acid (BA) added to the feed affects bone mineralization of weanling pigs, and that a wide dietar...
Estimation of the Optimal Ratio of Standardized Ileal Digestible Threonine to Lysine for Finishing Barrows Fed Low Crude Protein Diets
Threonine to Lysine Ratio Standardized Ileal Digestible Performance Low Crude Protein Pigs
2016/5/12
Two experiments were conducted to determine the standardized ileal digestible (SID) lysine (Lys) requirement and the ideal SID threonine (Thr) to Lys ratio for finishing barrows. In Exp. 1, 120 barrow...
Effect of Aflatoxin on Feed Conversion Ratio in Broilers: A Meta-analysis
Aflatoxin Feed Conversion Ratio Broilers Meta-analysis
2016/5/9
Aflatoxins are natural contaminants of poultry feeds and feed ingredients and cause liver damage, immunosuppression, reduction in performance and mortality in broilers. A number of studies have been c...
Effects of Dietary Energy Concentration and Lysine on the Digestible Energy Ratio for Apparent Amino Acid Digestibility in Finishing Barrows
Barrows Lysine:DE Ratio Amino Acid Digestibility Urinary Nitrogen
2016/4/27
This experiment was performed to investigate the effects of two energy levels and four lysine:digestible energy (DE) ratios on the apparent digestibility of nutrients in finishing pigs. The experiment...
